The invention discloses an under-train box body of a maglev train. The under-train box body of the maglev train comprises a box shell, a power module and an electrical element; a first cavity and a second cavity are formed in the box shell, and a first opening is formed in the first cavity; the power module is arranged in the first cavity in a sliding mode and can slide out of the first cavity through the opening under the action of external force, and the electrical element comprises a first type of electrical components, a second type of electrical components and a third type of electrical components; the first type of electrical components are electrical parts with high probability of faults, the first type of electrical components are integrated on the same circuit board, and the circuit board is arranged on the power module; the second type of electrical components are electrical parts with secondary probabilities of faults, and the second type of electrical components are arranged on the end surface of the box shell; the third type of electrical components are electrical parts with low probability of faults, and the third type of electrical components are arranged in the second cavity of the box shell. The technical problem that in the prior art, the electrical element in the under-train box body are difficult to disassemble, assemble and maintain is solved.
